Update on Setagaya 7.356 Microsieverts/Hr Spot: Only Horiba Survey Meter Detects

The person who posted the 7.356 microsieverts/hour spot at the gate post in front of a high-rise apartment in Setagaya-ku has an update.

He says when the measurement was done again with the Setagaya-ku government people on the same spot, only his survey meter, HORIBA Radi PA-1000 , responded. The Setagaya-ku government used "NHC7" made by Fuji Electric.

Their temporary conclusion is that for some reason the HORIBA Radi PA-1000 was picking up some electrical source inside the gate post.

Were both geigers set up for all forms of radiation? Alpha?

Probably not. I'll ask the person.

Most environmental radiation consists of three types: alpha rays (α), beta rays (β) and gamma rays (γ). HORIBA's PA-1000 "Radi" environmental radiation monitor makes it easy for non-specialists to measure even minute levels of gamma rays.
